Parasocial?

I have never even heard the word "parasocial," but it is Cambridge Dictionary's Word of the Year.  Okay, the article says parasocial relates to "a connection that someone feels between themselves and a famous person they do not know, a character in a book, film, TV series, etc., or an artificial intelligence."  Since I've never "adored" a celebrity, I guess that could explain why I've never heard the word.
